this invention is to so ordinary construction.

the inventionconsists'in the telephone trans in which like characters ofreference indicate ure'l'is a sectionalelevation of a telephonethisinvention; and, Fig; 2'i's a front elevation "In- ;these'dra -ngs 5represents the ordishoul r of the front plate of the diaphragm servestegbind'the contracted inner ed e of' an annularireceptacle il between'it'an the tracts at the edges of the central opening. therethrough'anrfo'rm's acontainer for a disinfectant, 10,.Which may be in a liquid ora" dry form; The gases 'or fumes from the .disinfect ant'pass'throughpassages 1; in. the contracted inner edge oft e receptacle ton I groovearound the neck, 10fv thefmouth piece a and then through radialperforations 12mm the interior or the throat of themou-th piece.

In order that the disinfectant maybe easily placed'into the receptacle 9said receptacle 'isprovided with a capped opening 13at;
